Abstract

The new triterpenoid saponin, 3-O--L-rhamnopyranosyl-(12)--L-arabinopyranosyl-
(12)- -D-xylopyranosyl-taraxast-20(21)-en-28-oic acid-28-O-2-O-R- -D-glucopyranosyl
ester has been isolated from the roots of Zygophyllum dumosum. The structure was established
primarily by NMR spectroscopy. All NMR signals were assigned by 1H-1H COSY, HMQC,
HMBC, ROESY and TOCSY experiments.
